Abstract
A gate array type semiconductor device including at least a plurality of basic cell arrays and diffusion regions for suppressing latchup in the basic cells forming the basic cell arrays. Each of the diffusion regions has a comb-shaped structure, i.e., wide tooth parts, narrow tooth parts, and a base part, formed as an integral structure. These parts partially surround each basic cell.
